Mouse, you paid a lot for your lights. I got mine with bulbs, built in ballast so you can run directly from the mains. 165 quid the three. We got a bit of a deal because we paid cash. Two metal halide and one hps all at 400w. You need to shop around, grow shops are extortionate. Just see what they are selling that you need, then get it cheaper somewhere else. That's my motto.
Sorry farmer, definitely will not work.
